Transparent Interconnection of Lots of Links (TRILL):
Vendor-Specific RBridge Channel Protocol
Abstract
The IETF TRILL (Transparent Interconnection of Lots of Links)
protocol is implemented by devices called TRILL switches or RBridges
(Routing Bridges). TRILL includes a general mechanism, called an
RBridge Channel, for the transmission of typed messages between
RBridges in the same campus and between RBridges and end stations on
the same link. This document specifies a method to send vendor-
specific messages over the RBridge Channel facility.

1. Introduction
The IETF TRILL (Transparent Interconnection of Lots of Links)
protocol [RFC6325] [RFC7780] is implemented by devices called TRILL
switches or RBridges (Routing Bridges). It provides efficient least-
cost transparent routing in multi-hop networks with arbitrary
topologies and link technologies, using link-state routing and a hop
count.
The TRILL protocol includes an RBridge Channel facility [RFC7178] to
support typed message transmission between RBridges in the same
campus and between RBridges and end stations on the same link. This
document specifies a method of sending messages specified by a
particular organization, indicated by OUI (Organizationally Unique
Identifier) [RFC7042] or CID (Company Identifier) [802], over the
RBridge Channel facility. Such organization-specific messages could,
for example, be used for vendor-specific diagnostic or control
messages.

However, note that a range of RBridge Channel protocol numbers are
available based on RFC publication. Those intending to use the
RBridge Channel facility are encouraged to document their use in an
RFC and to use RBridge Channel protocol numbers based on such RFC
publication.
